The following observations where for our Bullet ll speaker. Our new speakers will follow in it’s footsteps.

We’ll start with the wiring issue.

This obsession started in 2007. The Bullet ll being 2 years in the making. At that time we ordered multistrand copper, multistrand silver coated copper, and the very expensive multistrand silver wire.

Throughout our first 3 1/2  years we heard an anomaly which we couldn’t explain, or get rid of.

A memory from years ago magically appeared. If I am not mistaken, I saw a picture of a crossover. This crossover was from a magical mini 2-way built by a Wolf of a man. It showed magnet wire being used in his $20,000.00 speaker (pennies a foot? but it sounded great).

It was at that moment that I removed my multistrand, and replaced it with a very inexpensive single strand copper. THE ANOMALY WAS GONE!.

This is the configuration we took to TAVES 2013. I will add some of the comments from the show in a ‘Review’ section.

Bigger is not better when it comes to the transfer of music from one place to the next. In our listening experience, the smallest guage wire you can get away with sounds the best.

If you are able, take your own crossovers out of your speakers. If there is any multistrand, replace it with very simple solid core. Your tweeter needs only 22 awg or 24 awg, nothing larger. Experiment for yourself if you don’t believe me. 16 awg or 18 awg for the midrange.

DIGITAL OBSERVATIONS

I won’t bore you with the details.

CD’s are not always enjoyable. Make sure you have  a great player, and well recorded/produced CD’s. Great CD’s are the JVC XRCD.

SACD’s (which have a dual layer) have way more information, and sound great.

Vinyl puts the performers in the room with you (look at our ‘review’ section, we played only vinyl).

I have listened to the ExaSound e20. This was in my listening room, and George from exaSound was quite accommodating. WE HAVE SINCE PURCHASED THE EXASOUND E22. IT’S AMAZING.

No Sir, I’m not a conspiracy theorist?

Lets look at woofers. Lets look at amplifiers.

The following are pictures of 15″ woofers impedance curves. The first is the AE TD15M, followed by some ‘Enjoy the Music.com’ measurements. BD15, Magnum 15HO, 2226H.

Look at those impedance spikes. Our woofers have huge impedance’ at certain frequencies. Often at those frequencies we want to be loud.

Lets look at solid state amplifiers.

Lets look at a truly remarkable, the best the solid state camp can produce, 500Watt monster rated at the top of the heap. Gods gift to audio.

It makes 500watts at 8 Ohms.

It makes 1000watts at 4 Ohms.

It makes 2000watts at 2 Ohms.

It makes 4000watts at 1 Ohm.

What a fabulous amp. I’ll take two?

WAIT A SECOND.

What about our woofers?

They are not 1 Ohm, they’re 100 Ohms. This in that ‘wanted’ 20 – 40Hz range.

Lets look at our perfect solid state,………box.

250watts at 16 Ohms

125watts at 32 Ohms

62.5 watts at 64 Ohms

31.25 watts at 128 Ohms.

HOW ABOUT A TUBE AMP?

We use the Atma-Sphere MA-1 OTL (output transformerless) amplifier. 140 watts @ 8 Ohms. Our amp appears weak by comparison.

135 watts at 4 Ohms. (a far cry from 1000Watts)

BUT WAIT!

160 watts at 16 Ohms. We like this.

Output rising slightly more as the impedance rises. If memory serves me. There was a time when all amplifiers where tubes. Speakers where 500 Ohms (that wasn’t a misprint).

As the frequencies go down, our woofers impedance rises.

As our woofers impedance rises, our tube amplifier gets stronger. The woofer gets louder and louder.

The doubling of power gives +3dB of volume.

+3db of volume is TWICE as loud.

Some of the impedance graphs are well above 100 Ohms.

Our tube amp makes 160+ watts at 100 Ohms.

A solid state amp makes around 40 watts (that’s starting at 500 watts). This might be the reason why 1500+ watt plate amps need to be used. With a high power plate amplifier we get 120 watts to our woofers at 20 -40 Hz. Still not the 160 watts with our high power tube amp.

Our tube amp is potentially three times louder in the low end when compared to a 500 watt SS amp. Add another 3dB of transient attack, and, well, this is just too much to believe. At this point these are just words on a page. Wait till you hear it for yourself, or someone you know and trust has heard them.

Every Audiophile should make their buying decisions based on what they hear, not on what they’ve read. This includes my speakers. Come for  a listen.
